When i play music loud the sound cuts out

When sub-woofers are overdriven (played too loud) they create a lot of heat. You can try using an external fan or improve the ventilation around the speakers. Most good speakers have thermal cut offs that prevent permanent damage.

Step 1:

Overheating is typically caused by poor ventilation. The best thing is to make sure that you --

Step 2:

have plenty of space ALL-AROUND the amp

Step 3:

Fan(s) are working correctly (should always be on).

Step 4:

Boards are clean -- may require opening up housing and spraying with compressed air.

Step 5:

Be sure that the speakers you're pushing are acceptable to amp's output.

Step 6:

If still overheating, may require service.

sounds like your speaker is either the wrong resistance for your amp ie your amp may state 4 ohms and your speaker is 2 ohms which means that the speaker is shorting out the amp and its going into protection mode or the speaker could be burning out and shorting out the amp

does your bass have active pick ups?
do the ratings on your amp match the ratings on your speaker?
are you using a pedal?
does your pedal have an output adjustment?
have the ground on your bass checked.
make sure you're using the right kind of cable.
and be sure that the outlet you're using is grounded.

There is a protection thermistor in the circuit to keep it from over-heating, this is why it works again when it cools. Check and make sure you are not covering any ventilation holes, or if the unit has a fan, make sure it is working.

ALL THAT IS NOT YOUR PROBLEM CHECK ALL YOU POWER SOURCE AND IF ALL OK CHECK TO SEE IF ANY SPEAKER IS BAD OR GROUNDING OUT'' THE CAN COURSE THAT TO HAPPEN AND CHECK MAKE SURE RCA IS NOT PINCH ANY WHERE

hello. we cant help if we dont know what music source you are using.

check your ground wire and your remote wire, Wiggle them separately both at the amp and at the ground point. See if it cuts out then, and you;ll know which one. Also, does it have a light on it when it cuts out? if so, it could be going into protect mode, which wont allow it to turn on for a period of tine. Make sure the amp is not too small for the speakers you are pushing.
NGK

Check operations manual for indications as you described. Amps MUST have adequate ventilation. Make sure unit is not in small, semi- closed space or on top of other warm equipment. Check for speaker impedences match that of amp

UNPLUG THE GREEN WIRE FROM THE COMPUTER AND PLUG IT INTO A CD PLAYER IF IT WORKS BETTER ON A CD PLAYER THAN THE COMPUTER IT SELF THERE MAYBE A PROBLEM WITH THE SOUND CARD AND ALSO TRY THESE STEPS I AM GOING TO GIVE YOU I AM SURE ONE OF THEM WILL WORK.

1. Please ensure that the all the connections between the satellite speakers and the subwoofer are firmly connected.
2. Next, please connect the green colored 3.5mm audio jack to another audio device such as an iPod or an MP3 player.
3. Ensure that the SoundTouch remote control is firmly connected to the back of the subwoofer.
4. Connect the power cord from the subwoofer and connect it to another single power outlet in your house. If you have an automated voltage regulator (AVR), please connect the power cord through the AVR instead of connecting it directly to a power outlet in your house.
5. Power up the speaker system and check whether the power button on the SoundTouch remote control will light up.
6. Turn on the Matrix Mode ON. This option is on the SoundTouch remote control. This is to ensure all speakers from the speaker system will produce audio that will be played from the audio device.
7. Play audio from the audio device. Check and see whether the all the speakers will produce audio being played from the audio device.
